White House posts footage of Obama tweeting

The White House has posted footage of President Barack Obama tweeting (see below) during his Monday Q&A on Twitter about the Fiscal Cliff - the first time a Commander and Chief has taken to a social network to push his case in a stand off with Congress, or indeed to push any case.

No doubt the footage is indeeded to emphasise that it was the President who tweeted during the session.

But his quote suggests it might have been the first time he was driving the account personally, as he seems intrigued when he sees his words actually display on Twitter.
